27 Claims.

The present invention relates to a control for a record handling and copying apparatus and more particularly to a sequential control means operative during starting and stopping of said apparatus to maintain operation of a photographic copying machine for an interval before the starting and after the stopping of a record handling means.

The preferred construction and arrangement of the photographic copying machine and record handling means are shown in the copending application of Alvin E. Schubert and Harvey P. Hintz, Serial No. 471,706, filed January 8, 1943, for Record handling and copying apparatus. However, the sequentia1 control of the present invention is equally effective for any type of record handling means and photographic copying machine. While the aforementioned application discloses sequential stopping of a record handling and copying apparatus so that the copying machine is stopped only after the records therein have been photographed, it is also necessary and desirable to start the photographic copying machine for an interval prior to starting of the record handling means so that the copying machine will be up to normal speed for proper exposure and proper spacing of the records therein. Furthermore, the interval timing means or sequential control for stopping the record handling means prior to the photographic copying machine according to said copending application is of comparatively complicated and expensive construction.

The primary object of the present invention is the provision of a sequential control means for record handling and copying apparatus operative during starting of the apparatus to start said copying machine before the record handling means is started and operative upon stopping of said apparatus to stop the record handling means before saidcopying machine is stopped.

Another object of the invention is the provision of a sequential control for starting the copying machine before the record handling means is started.

A further object of the invention is the provision of a sequential control means and of a protective means for rendering said sequential control inoperative during normal operation of the apparatus or after the apparatus has stopped.

Still another object of the invention is the provision of a sequential control means including a thermo-responsive member for delaying the starting of the record handling means until a predetermined time after the copying machine has been started and/or for. maintaining the I copying machine for an interval before the rec- 0rd handling means is started and/or for maintaining operation of the copying machine for an interval after the record handling means is stopped.

Another object of the invention is the provision of a sequential control means including a thermo-responsive member and/or an interval timer assembly respectively for maintaining operation of the copying machine for an interval before the record handling means is started and/or for maintaining operation of the copying machine for an interval after the record handling means is stopped.

Other and further objects of the invention will be suggested to those skilled in the art by the description which follows:

The above and other objects of the invention are embodied in a sequential control for a photographic copying machine and for a record handling means for delivering records to said copying machine and including a timing assembly for maintaining the operation of the copying machine for an interval before said record handling means is started and. including a second timing assembly for maintaining the operation of said copying machine for an interval after said record handling means has stopped, either or both of said timing assemblies being a thermoresponsive device or an interval timer. In order to preserve or prolong the life of such timing assemblies it is necessary that they be rendered inoperative during normal operation of the apparatus and after sequential stopping thereof. Furthermore, the thermoresponsive type of timing assembly can be of inexpensive-but rugged construction to reduce the original cost and maintenance of the sequential control of the invention.

Reference is hereby made to the accompanying drawings wherein similar reference characters designate similar elements and wherein:

Fig. 2 is a diagrammatic illustration of the drives for the feeding means, copying machine and camera.

document or card 62 on the platform 6| Such reciprocation of the feeder heads 64 moves such lowermost document of the stack 82 between a pair of rollers 83 and into and through the guiding throat 84. The lower roller 83 is drivenand is mounted upon a shaft 85 which carries a worm wheel 85 meshing with a worm 81 on said drive shaft I5.

The record handling means may also include a continuous conveyer which has an arcuate path and which moves the documents continuously in spaced relation through such arcuate path and delivers them into the entrance of the document feed of the photographic copying machine, Said conveyer is mounted between side plates 88 which are mounted upon and extend from the feeder frame 58 and each of said side'plates 88 carries a bracket 89 having an arm 90 and a foot 9i. A shaft 92 is journaled in side plates 88 and carries a pair of wheels 93 having their peripheries covered with a frictional material. Polished and fixed guide members are mounted in between wheels 93 and between each of wheels 93 and side plates 88. Specifically, a polished guide member 94 has its ends fastened to feeder frame 50, and has a cylindrical intermediate portion concentric with but slightly below the eripheries of wheels 93.

The driving assembly of the continuous conveyer comprises a pair of endless belts extending around a series of pulleys and bearing against a part of the peripheries of wheels 93. There are three pairs of pulleys, only one of which is driven. A shaft 95 is also journaled between side plates 88 and carries a pair of pulleys, not shown, but arranged to engage a pair of idler rolls 96 mount ed on a transverse shaft 91' which is also journaled in side plates 88. A worm wheel 91, see Fig. 2, is mounted on one end of shaft 95 and meshes with a worm 98 on the end of drive shaft I5. A sprocket 99 is mounted on the'other end of shaft 95. A shaft I is mounted within slots in arms 90 and carries a pair .of freely rotatable pulleys IN. A stay rod I02 is connected between the outer ends of arms 30. A shaft I03 is rotatably journaled in extensions, not shown, of brackets 89 and carries a pair of pulleys I04. A pair of endless belts I05 each encircle said pulleys on shaft 95, pulleys IN on shaft I00 and pulleys I04 on shaft I03 with the belts running with a portion of each belt bearing against the peripheries of wheels 93 to form a circular arcuate path within the continuous conveyer. A sprocket I06 is mounted on the end of shaft I03 and an endless chain I0'I encircles sprockets 99 and I05 so that shaft I03 and pulleys I04 are driven. Thus, the endless belts I05 are driven only at one point or by the pair of pulleys I04 so that the endless belts I05 are placed under tension only in those portions contacting the peripheries of wheels 93 or the records 52 therebetween. A sheet metal housing I08 is mounted upon oneof side plates H0 threaded into feet 9| and held in adjusted records consecutively without changing their se- 0 portion of said central support I I8 abuts against quence. Such receiving means includes a hopper having side walls II2 fastened to ledge I8 and a horizontal platform II3 supported from bracket H by a cross member II4. A follower assembly comprises a follower plate II5 having ears I Is on which rollers I I! are mounted and includes a central support II8 having a portion extending below platform H3 and carrying rollers II9 engaging the undersurface of platform II3. Said follower assembly is consequently movable along said platform II3 with follower plate H5 in upright position and said follower assemblyis biased or normally urged toward the periphery of the document feeding drum Is in a well understood manner, preferably by a weight, not shown.

An abutment means for the records or cards is positioned within the receiving means to engage the leading edge of the records and to arrange'them in edgewise relationship within the receiving hopper. Such an abutment comprises polished flanges I20 fastened to the side walls II2 of the receiving hopper and spaced from the card supporting surface of platform H3 2. distance corresponding to the dimension of the recorcls in their direction of travel through the apparatus. For the purpose of insuring removal of the record from the document feed of the copying machine a stripper means maybe provided. Specifically, stripper arms I2I are mounted on flanges I20, being preferably formed integrally with flanges 20, and extend downwardly preferably into recesses in the surface of drum I9. When the receiving hopper is full the depending the plunger I22 of a normally closed switch I23 to open the same for initiating a stopping cycle of the apparatus as will be later explained.

The sequential control means of the present invention are operative during the starting cycle and stopping cycle of the record handling and The carriage assembly including the feeder,

conveyer and common drive means therefor, fills v the opening in the front of the casing I0 of the copying machine and is hinged so that it may be readily swung upwardly for inspection, adjustment and/or repair of the feeder, conveyer, and/or document feed of the copying machine. The operative position of such carriage assembly may be varied by adjustable means comprising resilient pads I09 mounted on the ends of screws copying apparatus. The initiation of such starting or stopping cycles may be caused or prevented by a plurality of other controls, some of which may be manually operated and others of which are necessary to unattended operation of the apparatus; Such other controls are the normally open switches of the camera 42 which are closed when'the camera 42 is improperly located or upon occurrence of an improper film condition therein, a cranking assembly for winding a predetermined length of film through said camera 42 upon opening or closing of the rear cover I8 and preventing operation ofthe motor 5| of the copying machine, a full hopper control means to stop the apparatus or to prevent starting thereof when the receiving hopper is full. and/or a record controlled means operative. to stop the apparaitus or prevent starting thereof when there are no records or the records are improperly spaced in the record handling means.

The operating circuit of the copying machine motor 5| and the circuits providing the aforementioned manual or automatic controls are the same for all modifications of the invention and will now be described with respect to Figs. 3, 6 and 7. The main supply lines I24 and I25 are connected through fuses respectively to connector blocks I25 and I21.

The operating circuit for the copying machine motor 6! extends from main supply line I23 to connector block I 26 through wires I26, I29 and I35 to a switch I3I and thence through a wire'i32 to a connector block I33, wire I34, connector block I35, wire I36 to said motor the other side of motor SI is connected by a wire I31 to a connector block I36, wire I39. main switch I40, connector block I21 and the other main supply line I25. Thus, it will be seen that the energization of the copying machine motor 5 I is principally controlled by the switch I3I but may also be controlled by the main switch I40. The operating circuit for the motor 82 of the record handling means extends from main supply line I24, connector block I 26, wires I28, I29, and I30, switch I3I, wire I32 and connector block I33 through a wire IM to one side of said motor 82 and the other side of motor 82 is connected through a wire I42, switchcontacts I43 and wire I44 to the wire I31 and thence in common with the operating circuit for the motor 5| to the main supply line I25. Thus, completion of the control circuit for said motor 82 requires closing of the switches I3I and I43.

' The primary control circuit includes the sequential control means for starting the apparatus and which may have various forms but also includes several manually or automatically controlled switches responsiv to a predetermined condition of the apparatus. Such control circuit extends from main supply line I24 through connector block I26, wire I28, switch arm I45 of a doublepole manually operable and normally open switch I46, wire I41, wire I48, connector block I49, wire I50, switches R1, R3 and I23, wire I5I and the timing assembly to be later described, the relay coil R2, wire I52, wire I44 and wire I31 and thence in a manner already traced to the other .main supply line I25. Such primary control circuit may be interrupted for any of several reasons.

For instance, improper location of or an abnormal film condition in the camera 42 closes in a known manner any one of switches 41, 48, 49

or 50 to complete a circuit from ground I53, the

coil R3 of a relay, connector block I54, the sec- I62 connected through either of cam operated switches I63 or I66 and through a single pole double throw switch I65, which is automatically moved from one position to the other by respective opening or closing of the rear cover of the copying machine, and to the main supply line I25. In operation when said cover It is closed switch I65 is moved to completethe circuit through 'cam operated switch I63 and winding motor I62,

such winding operation being interrupted after a predetermined length or leader has been wound through the camera 62 and by opening of said camera operated switch I63 which is accompanied by the closing of the camera operated switch I64. When the cover I6 is open the switch I 65 will be returned to the position shown in Figs. 3, 6 and 7 whereupon the winding motor I62 is again energized to wind a length of film through camera 42 of the copying machine until cam operated switch I64 is opened. The coil of relay R1 is connected in parallel with winding motor l62 and so as to be energized and de-energized therewith upon the operation of switches I63, I64 and I65 as just described. Since the normally closed switch R1 of the primary control means is opened by energization of the relay coil R1 it is not possible to start or maintain operation of the apparatus when the auxiliary film winding means is operative. a

In a similar manner the primary control circuit, is also interrupted when the receiving hopper is full and when, in a manner already described, the central support H8 engages plunger I 22 to open switch I23 which is in series in the primary control circuit.

An automatic control is provided to stop the record handling means when there are no records ondary winding I55 of a transformer T, connector block I56, any one of said switches 41, 48, 49, or to ground I51. The primary winding I58 of said transformer T has one side connected through a wire I59 to connector block I38 and thence to main supply line I25 while the other side of said primary winding I58 is connected through a wire I60, through connector block I35, wire I34, wire I32, switch I3I, wires I30, I29, I28, connector block I26 to the other main supply line I24. A buzzer I6I also connected to ground hecomes operative upon the closing of this local camera circuit. Energization of said local circuit by closing of any of switches 41 to 50, inclusive, energizes the coil of relay R3 and opens thenormally closed switch R3 of the primary control circuit.

The copying machine is preferably provided with an auxiliary film advancing means for winding a predetermined length of film through the camera for the purpose of winding a leader or film exposed while loading the camera onto the takeup and also for winding a predetermined length of film or traileronto the take-up prior to opening of the" camera. Such auxiliary winding means may be automatically operated and may be constructed as shown in Schubert U. S. Patent No.

or cards in the document path of the continuous conveyer or when the records or cards are im-' properly spaced therein. Such a control means is shown in some detail in Fig. 5 and preferably comprises a pair of bell cranks I66 pivotally mounted by screws I61 on one of side plates 88. One arm of each bell crank I66 projects through recesses in the polished guide member 84 and into the document path of the conveyer. the other arm of each bell crank I66 being located to engage and close the normally open'switches I68. Said bell cranks I66 are placed in spaced relation along the document path of the conveyer and are located so that at least one of said switches I68 will be closed when properly spaced records 62 are moving through said document path and so that both of said switches I68 will be opened if there is improper spacing between said records or if there are no records 62 in the document path of the conveyer.

During normal operation of the record handling means the primary control circuit extends from main supply line I24, connector block I26, wires I28, I29. and I30, switch I3I, wire I32, connector block I33, wire I4I, either or both of switches I68, and a normally closed manually operable switch I69 to wire I48 and through the primary control circuit as previously described. It will now be evident that the switch arm I45 of the double-pole starting switch I46 is for the purpose of shunting the card-operated switches I68 for completion of the primary control circuit during starting and when there are no records or the records are improperly spaced to close at least one of switches I66. An improper spacing of the records or absence of records from the record handling means therefor opens both of 5 switches I68 to interrupt the primary control circuit and to initiate sequential stopping of the record handling and copying apparatus in the same manner as is accomplished by closing of switches 41 to 50 and opening or'switch Ra, by the operation of the auxiliary film winding means and opening of switch R1, or by opening of switch I23 when the receiving hopper is full. Furthermore, the switch I69 may be manually opened to interrupt said primary control circuit.

As before mentioned, the sequential control means of the invention may be provided in any of several different forms. The preferred form of such sequential control means is illustrated in Fig. 3 and will now be described.

The preferred form of the sequential control means for the starting cycle is connected in the aforementioned primary control circuit and comprises a heater coil- I10 in parallel with and adjacent to a thermo-responsive switch "I which are connected by a wire I12 through a switch I13 and wire I14 to one side or the relay coil R2, the other side of relay coil B: being connected in amanner previously traced by wires I 52, I44, I31, etc. to the main supply line I25. The voltage drop in heater coil I10 may be sufllcient to prevent energization of relay coil R: which is suflicie'nt to operate the plunger I15 and the switches thereon. However, a variable resistance circuit may be provided to control the critical energization of coil R2 and may comprise a switch 518 on plunger I18 and a variable resistance I11 which are shunted across the coil R2. When the heater coil I10 has raised the temperature of thethermoresponsive switch "I sufliciently to cause closing thereof, said heater coil I10 is shunted and the critical energization of the relay coil R2 is provided so that plunger I15 is operated from the position shown in Fig. 3 to move switch arm I18 thereon to close switch contacts I43. Such closure of switch I43 completes the operating circuit for the motor 82 of the record handling means which thereby becomes operative after an interval or predetermined time following ener gization of the motor of the photographic copying machine.

The heater coil I and thermo-responsive switch I1I may remain in the primary control circuit throughout its energization but the operation of such coil and switch and prolongation of their service period may be assured by providing a protective means to place them on open circuit after their functioning for sequential starting. Such protective means comprises a bypass circuit comprising a wire I19 and switch I80 mounted on plunger I15. Movement of plunger I by energization of coil R2 opens switch I13 to place heater coil I10 and thermo-responsive switch I1I on open circuit and closes switch I80 to maintain the primary control circuit through wire I19 and continued energization of coil R2. At the same time switch I18 is opened to place the variable resistance I11 on open circuit to preserve its operability and life.

The sequential control means for the stopping cycle may comprise a timing assembly including either a thermo-responsive member as shown in Figs. 3 and 6 or an interval timer assembly as shown in Fig. 7. The preferred form of tne sequential control-means for the stopping cycle is shown in Fig. 3 and comprises a'relay coil R4 having one side connected by a wire I8I to the wire I29 and thence to the main supply line I24. The other side of coil R4 is connected through switch contacts I82 and a switch arm I83, through a heater coil I84, through a wire I85, connector block I85, wire I81, switch contacts I88 normally closed by the switch member I89 constituting the second pole of the manually operated switch I46, through a wire I90, switch contacts I9I adapted to be closed by the switch arm I18 on plunger I15, and thence through wires I44, I31, and in a manner already traced to the other main supply line 125. A thermo-responsive switch I92 is shunted across a heater coil I84 and is positioned so as to be heated thereby. As before, the voltage drop across heater coil I84 may be sufficient to prevent critical energization of relay R4 or a loading resistance I93 may be connected through switch contacts I94, switch arm I95, and wire I96 in parallel with relay coil R4. Also for the purpose of protecting the thermo-responsive timing assembly a wire I91 and switch contacts I98 are arranged to by-pass the heater coil I84 and thermo-responsive switch I92 when the plunger I99 of the relay R4 assumes a position corresponding to energization thereof. Said plunger I99 of the relay R4 carries switch arms I3I, I83 and I95 and-said plunger I99 is normally biased so as to close switch I3I and so that switch arms I83 and I95 respectively close switch contacts I82 and I94. When coil R4 is energized, plunger I99 is moved to open the switches just mentioned and so that switch arm I83 closes switch contacts I98.

The operation of the sequential control means of the thermo-responsive type both for the starting and stopping cycles of the record handling and copying machine will now be described. As-

. suming that the apparatus is stopped, the plunger I'I5 and switches thereon of relay R2 and the plunger I99 and switches thereof of relay R4 Will be in the positions shown, in Fig. 3 and switch I3! is closed. Further assuming that the camera 42 is properly located and that all film condi tions therein are normal, relay R3 will be deenergized and switch R: will be normally closed. Also if the auxiliary film winding means is inoperative, switch Ri will be normally closed. If the receiving hopper is not full, normally closed switch I23 will be closed. Manually operable switch I69 is normally closed and card-controlled switches E68 may be closed or opened depending respectively on whether or not there are cards in the record handling means. If both of switches I68 should be open, it will be necessary to press the plunger of the double-pole switch I48 so that switch arm I45 thereof engage the associated contacts. Under these conditions, the primary control circuit Will be completed through the various switches just enumerated, heater coil I10, wire I12, switch arm I13, wire I14, relay coil R2. which will not be energized to its critical value, wire I52, wire I44, wire I31, connector block I38, wire I39, main switch I40, connector block I21 to main supply line I25. At the same time the operating control circuit through the motor 5| for the copying machine is completed and the copying machine will start to operate. As soon as the heater coil I10 raises the temperature of thermo-responsive switch I1I so as to close the same then relay coil R2 is energized at or above its critical value and plunger I15 is moved so that switch arm I18 bridges switch contacts I43. Such closing of switch contacts I43 completes the operating circuit to the motor 82 for the record handling means but the interval provided by the thermo-responsive assembly has been sufficient to permit the motor SI and the photographic copying machine to attain a normal running speed and so that the records being fed from the record handling means into the photographic copying machine will'be properly exposed and will be properly spaced because the copying machine and record handling means are operating at-synchronous speeds. At the same time switch I13 is opened and switch I80 is closed to place the heater coil I10 and thermo-responsive switch Ill on open circuit and to close the by-pass wire I19 through switch I80. Also switch I16 is opened to open the circuit through variable resistance The record handling meansand photographic copying machine will continue to operate in thi manner until some abnormal condition occurs or until normally closed switch I89 is manually opened.

Immediately upon the opening of any of switches Al to B, switches R1, Re, I23, I68 or both of switches I68, the primary control circuit is interrupted and relay coil R: is de-energized so that the plunger I15 returns to its normal posltion whereupon switch I18 dis-engages switch contacts I43 and the operating'control circuit for the motor 82 of the record handling means is open and the record handling means stops im-= mediately. The switch arm I78 in normal position of plunger I75 and upon de-energization of coil R2 bridges switch contacts Idi and closes the control circuit through relay coil Rs as follows: main supply line lzt, connector block.

I26, wires I28, I29 and Isl, relay coil Ra, switch wire I85, connector block Idd, wire Idl, switch contacts I86 and switch member I89, wire led, switch contacts IQI and switch arm lid, wire ldil, wire ISE, connector block I88, wire I39, main switch Itll, connector blocl: Ill to the other main supply line I25. As previously explained, the voltage drop in heater coil ltd and/or in the loading resistance I93 prevents coil R4 from being critically energized. After an interval dc termined by the characteristics of heater coil Idd and of thermo-responsive switch I92, the latter is closed whereupon coil R4 is critically energized and plunger I99 is moved from its normal position. Such movement of plunger ltd by critical energization of coil R4 opens switch Itl which is in the operating circuit of the motor 5i for the photographic copyi g machine. Thus, the copying machine is shut down after an interval predetermined by the characteristics of the thermo-responsive timing assembly. At the same time switch I83 is moved to open switch contacts I82 and to close switch contacts ltd thus disconnecting heater coil I8tl and thermoresponsive switch I92 but maintaining the circuit through contacts I98, wire I97, wire I85 and as previously traced to the other main supply line I25; Also, switch I95 has-opened the circuit for the loading resistance I93.

Since switch I3! is maintained open by energization of coil R4 after completion of the stopping cycle it is necessary to interrupt the circuit through coil R4 in order to start the apparatus again. This is accomplished by the double-pole manually operated switch Ida which may be operated so that switch arm I35 by-passes the card controlled switches I68 and which also opens switch arm I89 to interrupt the circuit through coil R4. Thus, as soon as an abnormal condition of the apparatus or illm has been cleared, the manually operable switch I46 can be operated and the motor 5i will be started and the starting cycle will be initiated. As previously er:- plained, the theme-responsive timing assembly in the primary control circuit will cause i'elai aaoaara coil R: to become energized after a predetermined interval whereupon the operating circuit of the motor 82 of the record handling means is completed. By the arrangement just described there is provided a very simple, inexpensive and effective arrangement of a sequential control means for starting the copying machinebeiore the record handling means and for stopping the record handling means before the copying machine is, stopped and also various protective devices to insure the operability and prolong the life of the heating elements or therm'o-responsive members of said sequential control means;

The sequential control means oi the invention may alternatively have an interval timer in the primary control circuit to predetermine the interval between energization of the copying machine mnotor 5i and thestarting of the motor 82 for the record handling means. Such an arrangement is shown in Fig. 6 and introduces a few simple changes which will be described. The interval timer assembly is of standard construction and comprises a motor 266 arranged to move, after a predetermined interval of opera tion, a switch arm 2M from a normal position engaging a contact 292 into engagement with a contact 263. The primary control circuit in this modification of the invention extends from the switch 923, through connector block 2%, through wire 265, through timer motor Edd, through wires 2% and 2d? and through wire it? which may be readily traced to the main supply line I25. The other side of the primary control circuit has already been traced through switch arm Idd of manually operated switch ice or through record controlled switches 158 to main supply line I 2%. The operating circuit for motor at of the photo graphic copying machine is also completed as previously described through switch Isl of relay R4 and to the main supply lines 826 and I25. Thus, motors 5i and Edd will start operation simultaneously, it being understood, oi course, that all of the manual or automatically controlled switches or the primary control circuit are closed. However, the operating circuit for the motor 32 of the record handling means is not closed until after the interval required for timer motor 298 to move switch arm 2M into engagement wtih contact 2% whereupon motor 82 is connected by wire 298, contact 253, switch arm 2M, wire 25?, and thence to main supply line I25, the other side of motor 82 being readily traceable back through switch as: to the other main supply line I2d. In this manner sequential starting of the copying machine at a predetermined interval prior to operation'of the record handling means is obtained. When the primary controlled circuit is opened by reason of the opening of switches therein, timer motor tilt is de-energi'ted and switch arm 2M immediately switch contacts I82, switch arm I83, heater coil I8d, wire I85, switch contacts I88 and switch arm I89, wire I96, contact are, switch arm 2M, wire Edi, wire Itl, connector block I38, wire I39,

main switch I48, and connector block I21 to the other main supply line I25. The voltage drop of heater coil I84 and/or of loadingresistance I93 prevents critical energizationof coil R4 so that switch I3I remains closed until such time as thermo-responsive switch I3I is heated enough to close. whereupon, plunger I99 is moved to open switch I3I and the operating circuit for the copying machine motor I. At the same time switch arm I83 opens switch contact I82 and closes switch contacts I98 to by-pass heater coil I84 and thermo-responsive switch I92 and switch.

resistance I93. Energization of the coil of relay R4 may be maintained to keep switch I3I openand prevent starting of the motor 5| when renewal of operation is desired. Consequently, switch arm I89 of the manually operable switch I48 may be opened simultaneously with closing of starting switch arm I45 to permit the closing of switch I3! and the repetition of the cycles just described.

Although interval timer motors as now provided are not impaired to any extent by being stalled upon the line as happens in the modification shown in Fig. 6, it is nevertheless deemed better practice to provide a protective means for bypassing the timer motor after its timing cycle has been completed. The modification of the invention shown in Fig. 7 provides such a protective means for the interval timer assembly for th starting cycle and also provides an interval timer assembly for the stopping cycle. While the interval timer for the stopping cycle is not shown with a protective means it is to be understood that such protective means may be provided in the same way as is shown for the interval timer motor for the starting cycle.

record handling means and thence through wire I4I as just traced to the other main supply line I24.

The protective means for said timer motor 223 comprises a circuit completed by switch 228 and extending through wires 230, relay coil R5 and wire 232 t wire I4l back-to the main supply line I24. Completion of this protective circuit ener- Referring now to Fig. 7, the primary control I circuit extends from switch I23 through wire 209 to connector block 2I8, wire 2, relay coil R2, wire 2I2, wire 2I3, connector block I38, wire I39 and connector block I21 to main supply line I25. The relay coil R2 has associated therewith a switch arm 2I4 which in normal position engages a contact 2l5 but which engages a contact.

2 I8 when said coil R2 is energized. When all op-' erating conditions of the apparatus are-satisfied and the primary control circuit closed to energize relay coil R2, switch arm 2I4 engages contact 2I6 to complete a timer motor control circuit through wire 2", connector block 2I8, wire 2I9, switch arm 228, switch contact 22I, wire 222, timer motor 223, wire 224, wire I4I, connector block I33, wire I32, normally closed switch 225 operated by a second timer motor 228, wire 221 to connector terminal I26 and the other side of main supply line I24. Since the switch 225 of the second interval timer assembly is closed the operating circuit to motor 5I is also closed simultaneously with completion of the primary control circuit and energization of the coil of relay Ra. When switch arm 2 I4 engages contact 2 I8 to complete the circuit just traced, timer motor 223 is energized and after a predetermined interval closes its associated normally open switch 228. Such closing of switch 228 completes the operating circuit for the motor 82 of the record handling means, such operating circuit extending from one side of switch 228 through a wire 228, connector block 2I8, wire 2I1, contact 2I8, switch arm 2I4, wire 2I3, and connector block I38 to main supply line I25, the other side of switch 228 being connected by a; wire 230 and wire 23l to one side of the motor 82 for the gizes coil R5 and moves switch arm 220 from engagement with switch contact 22I to open the circuit to the timer motor 223 but at the same time to maintain the control circuit by moving switch arm 220 into engagement with a switch contact 233 which now completes the operating circuit for motor 82 from connector block 2I8 through wire 2|9, switch arm 220, switch contact 233, wire 23I to motor 82. Thus, circuit for timer motor 223 is opened but the operating circuit for .motor 82 and the protective circuit including relay coil R5 is maintained. As before, any interruption of the primary control circuit either by manually operated switch I69 or by any of the switches R1, R3, or I23 will open the primary control circuit whereupon switch 220 opens the operating circuit to motor 82, de-energizes coil R2 and switch arm 2I4 returns to normal engagement with switch contact 2 I 5.

When switch arm 2I4 engages switch contact 2I5 the circuit to the second timer motor 226 is completed from main supply line I24, connector block I28, wire 221, timer motor 226, connector block 234, wire 235, contact 2I5, switch arm 2I4, wire 2I3, connector block I38, wire I39 and connector block I21 to the other main supply line I25. Although the operating circuit for motor 82 has been interrupted, the operating circuit for motor 5| of the copying machine is maintained through timer assembly switch 225 until said timer motor 226 has operated for a predeter- I40 mined interval and opened said switch 225.

Opening of switch 225 interrupts the motor operating circuit for motor 5| and stops the copy ing machine. The starting cycle may again be initiated when the primary control is closed as by closing starting switch I45. Completion of the primary control circuit energizes the coil of relay R2, moves switch arm 2I4 out of engagement with contact 2 I5 to interrupt the circuit of timer motor 228 whereupon switch 225 is immediately moved to its normally closed position. It should be noted that the switch 228 associated with timer motor 223 is normally open until after a predetermined interval of operation of said timer motor 223, while switch 225 associated with timer motor 226 is normally closed until after a predetermined interval of operation of timer 228 to open said switch 225. Furthermore, when the timer motor of these assemblies is deenergized the switches return to their normal position in a well understood manner. The energization of coil R: by completion of the primary control circuit initiates the sequence of events previously described to energize timer motor 223 to close switch 228, to energize motor 82 and coil R5 for protection of timer motor 223.

Furthermore, other timing demeans may be provided by those skilled in the art, but it is to be understood that the scope of the invention is not limited by the illustrated dling means operably independent of said copying machine and for delivering records to said record moving means of the copying machine, of a sequential control means operative during starting and stopping of said apparatus to maintain operation of said camera, drive connection and record moving means of the copying machine for an interval before the starting and after the stopping of said record handling means.
